Firefox 9 and fancy JavaScript optimizations
Another six weeks have gone by, and another version of Firefox has been released. Still not officially "live," Firefox 9 improves on Firefox 8 with a JavaScript engine that’s up to 30 percent faster and, well, not a whole lot else. Mac OS X users will have a little more to gain, as Firefox 9 also includes two-finger gestures for backward and forward navigation on that platform.
The new version includes a number of bug fixes to improve stability and security, better support for HTML5, CSS, and MathML, and some improvements to its Do Not Track feature to allow scripts to know if tracking is enabled or not. All told, the new release includes more than one thousand bug fixes and improvements.
